The code is in oslo-incubator but does need to be synced across to Nova, so think we should keep a Nova task open

This can result in problems when making a conductor call that returns a large structure - for example, instance_get_all_by_host on one of my systems returns 38 instances, which when serialized as JSON is too long for Qpid to handle. There's a discussion of the limitation here: https://issues.apache.org/jira/browse/QPID-4583 I believe the best fix here is to wrap the string in a buffer as suggested in the link above. This works fine on my local system and seems to fix the problem (note: I haven't tested against RabbitMQ yet, and right now I put the change in common code so that will need to be done). However, that will be a backward compatibility breaking change because it will need to be handled differently on the receiving end as well.
